Here's a very interesting mob fight that I managed to initiate in my More Monsters add-on. Not only are the mobs fighting in unique ways due to their modded abilities, but they also coincidentally seem to be making expressions and reacting to the conflict in NPC-like ways throughout the video. If you like add-ons that add new mobs into the game and like what you see in the video below, you can download my add-on here: More Monsters Add-On
